Challenger is a drop-in JavaScript library that adds interactive programming challenges to any page. Challenges are flexible and expressive, and are super simple to write. A challenge has requirements based on code structure and program output, and gives users a code editor to experiment in. When new code is written, it's run in a sandbox and the output is analyzed. Challenges can be presented as one-off tests or linked together to form courses.

QUESTION
I have created a custom AWS authentication flow based on the following Github Repo
I want the verify-auth-challenge-response
Lambda to invoke a custom Lambda i have created which I am using to set the user's password. This is in a scenario where the user didn't have a verified email address. I don't want them to have to complete a verification code twice so want this new Lambda to set the password if the challenge is accepted.
I have modified the verify-auth-challenge-response
as follows
ANSWER
Answered 2021-May-14 at 08:54I am wondering if its related to async behaviour in the Lambda.
Probably. You are using async handler, so your function seems to finish before it has a chance to invoke the other function.
To overcome this you can wrap your code in the handler in new Promise
as shown in the AWS docs.
QUESTION
I am a newbie in data analysis. I wish to know how to boxplot multiple columns (x-axis = Points, Score, Weigh) in a single graph and make the y-axis as a standardized scale for comparison. I have tried and couldn't understand the code (Python+Pandas+Seaborn) for this. Help me out guys. The dataset for the same is as follows:
Cars Points Score Weigh 0 Mazda RX4 3.90 2.620 16.46 1 Mazda RX4 Wag 3.90 2.875 17.02 2 Datsun 710 3.85 2.320 18.61 3 Hornet 4 Drive 3.08 3.215 19.44 4 Hornet Sportabout 3.15 3.440 17.02 5 Valiant 2.76 3.460 20.22 6 Duster 360 3.21 3.570 15.84 7 Merc 240D 3.69 3.190 20.00 8 Merc 230 3.92 3.150 22.90 9 Merc 280 3.92 3.440 18.30 10 Merc 280C 3.92 3.440 18.90 11 Merc 450SE 3.07 4.070 17.40 12 Merc 450SL 3.07 3.730 17.60 13 Merc 450SLC 3.07 3.780 18.00 14 Cadillac Fleetwood 2.93 5.250 17.98 15 Lincoln Continental 3.00 5.424 17.82 16 Chrysler Imperial 3.23 5.345 17.42 17 Fiat 128 4.08 2.200 19.47 18 Honda Civic 4.93 1.615 18.52 19 Toyota Corolla 4.22 1.835 19.90 20 Toyota Corona 3.70 2.465 20.01 21 Dodge Challenger 2.76 3.520 16.87 22 AMC Javelin 3.15 3.435 17.30 23 Camaro Z28 3.73 3.840 15.41 24 Pontiac Firebird 3.08 3.845 17.05 25 Fiat X1-9 4.08 1.935 18.90 26 Porsche 914-2 4.43 2.140 16.70 27 Lotus Europa 3.77 1.513 16.90 28 Ford Pantera L 4.22 3.170 14.50 29 Ferrari Dino 3.62 2.770 15.50 30 Maserati Bora 3.54 3.570 14.60 31 Volvo 142E 4.11 2.780 18.60My output should look something like: Output Boxplot Graph

QUESTION
I am working on a Blazor server side .Net 5.0 application that allows a user to delete a user from Azure AD B2C after he has logged in. I am using the information contained in this article. I am getting a Message: Authentication challenge is required.
error.
What could I be missing?
Code to delete user using Azure AD B2C:
...ANSWER
Answered 2021-Apr-12 at 04:55It seems that you want to use Application token (you assign the Application permission in the app registration) to delete the user.
In this case you should use ClientCredentialProvider
rather than AuthorizationCodeProvider
.
QUESTION
I have created a reactive function in the server to get a list of elements. The idea is to show each element of the list as a individual choice in the ui, just like selectInput does in the ui.
I wrote an example with mtcars.

QUESTION
I am trying to parse this complex JSON data into a Flutter application. I am able to get the JSON data successfully, but not able to display the data in the application. See the code and JSON data below. What I am doing wrong?
...ANSWER
Answered 2021-Mar-23 at 22:56You can help in the construction of the classes with this application. (https://app.quicktype.io/)
These are the classes that you must use for the obtained object. Be sure to change the name of the classes that you think are relevant.
QUESTION
I am trying to subsample a data.frame in a way that the sample would have observations that capture as much variation as possible among a set of columns of the original data.frame.
An example with the mtcars
dataset: I'd like to find 3 cars that are the most different from each other by mpg
, vs
and carb
. Looking at the data visually, it would probably be Toyota Corolla (high mpg
, vs
1, low carb
), Cadillac Fleetwood (low mpg
, vs
0, medium carb
) and either Maserati Bora (low-med mpg
, vs
0, high carb
) or Ferrari Dino (medium mpg
, vs
0, med-high carb
):
ANSWER
Answered 2021-Mar-20 at 15:12I am not exactly sure if this is what you are looking for, but here it goes:
calculate a distance matrix, giving you information about how "far away" each car is from all other cars, based on all the attributes they have (the default for
dist()
is eucledian, which you can change).Then take the rowsums or colsums (same thing) from that matrix, which just sums up for each car what the combined distance to all other cars is.
Then isolate those cars with the biggest distances (here, we want 3 cars)
Finally subset your dataframe to only include those cars:
QUESTION
I'm using "tiles" to show content, clicking on a tile expands content. Within the expanding content, I'm using the left hand side for displaying text (spec-info
) and for the right hand side I'm using (icon-percent
) to display an icon. I'm happy with this outcome as the icon sitting at the right hand side is positioned well in comparison to the text. However when on smaller device sizes, (ipad, iphone) - the "split" view of using left and right would be reverted to full width with the icon scaling appropriately and displaying above the text. I'm familiar with media queries but not sure they're appropriate for this implementation? any ideas would be really appreciated! I've created a working fiddle here too: https://jsfiddle.net/6gsvjt4r/1/
ANSWER
Answered 2021-Mar-09 at 18:36There are a couple of things I'd suggest doing:
Remove fixed sizing on the .percent-icon-size image
I see in your CSS, you have the height and width set on
